Given numbers are 787,643,688,721,230

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 787,643,688,721,230 is 28867371986320.

Find LCM of 787,643,688,721,230 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 787 x 643 x 344 x 721 x 115 = 28867371986320

Therefore, the lowest common multiple of 787,643,688,721,230 is 28867371986320.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

787 x 643 x 688 x 721 x 230 = 57734743972640

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

787 : 1, 787

643 : 1, 643

688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688

721 : 1, 7, 103, 721

230 : 1, 2, 5, 10, 23, 46, 115, 230

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 787,643,688,721,230, is 1.

Now, the common factors can be found like this.

787:787

643:643

688:2x 2x 2x 2x 43

721:7x 103

230:2x 5x 23

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2 = 2

Therefore, the value for common factors is 2.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 57734743972640/(1x2)

LCM = 57734743972640/2

LCM = 28867371986320

Thus, we can understand that the LCM of 787,643,688,721,230 is 28867371986320.
